feat: Adding possibility to output all TableFunction in log/CSV + Solving a bug on PVT CSV export

[MelReyCG]

This PR aims to:

1. Add the possibility to write TableFunctions in the log or in a CSV file through logLevel="1" or writeCSV="1" (this feature has been requested by TE users),
2. Solves a bug on saving a PVT table to a CSV file when an output folder has not been created yet (by calling makeDirsForPath(), as it is done for other output files),
3. Slightly refactor the TableFunction code to remove any PVT concept from its class,
4. Slightly rewrite the writeCSV documentation to make it clearer.

Sorry to include such scattered work in the PR, but they are all small changes for TableFunction.

Currently,

• documentation is not completed,
• table layout is not optimal.
